Try loading your document into a DOM with either Xerces-C - actually C++ -
or Xerces - Java. It's not hard at all to write a program just a few lines
long to do that.
If your document is not conformant to XML, Xerces will complain.
If your format isn't that complex, it's not hard to write a DTD. There are
some open source packages that will do DTD validation now. DTDs are
written in SGML using metacharacters that aren't hard to learn. I've never
written an XML schema, but they're meant to be easier to write than DTDs,
yet provide stricter specification compliance. There are some open source
schema validators. The instructions for the DocBook 5 XML tell you how to
validate it with a Java validator, but I don't recall its name.
Best of luck,
Mike
